Abstract (en)
[origin: WO2019183870A1] The disclosure relates to a tie resin formulation with excellent adhesion to polyethylene terephthalate (PET). The resin includes (A) an ethylene acrylate copolymer formed from ethylene and alkyl acrylate, where the ethylene acrylate copolymer has an acrylate content of 10 to 30 weight percent and an ethylene content of 90 to 70 weight percent based on the total weight of the ethylene acrylate copolymer and the acrylate content and (B) a transesterification catalyst; where the resin includes: 30 to 99.999 weight percent of the ethylene acrylate copolymer based on the total weight of the resin; 0.001 to 10 weight percent of the transesterification catalyst based on the total weight of the resin; and (C) 0 to 69.999 of a non-polar polyolefin based on the total weight of the resin.
